Application filed July 6, 1912.

To all I1.0710211. t may con cer/'1 Be it known that I, lViLLIs E. ALLEN, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Syringes, of which the following is a specification.

This invention comprehends certain new and useful improvements in surgical instruments and appliances, and relates particularly to syringes of the expanding type.

The invention has for its primary object a simple, durable, and efficient construction of syringe of this character designed for vaginal use the parts of which are so con structed and arranged that they may be easilyand cheaply constructed and readily assembled and not liable to get out of order.

A further object of the invention is an improved vaginal syringe which will not be liable to injure the walls of the vagina,

whichin operation will thoroughly Hush the;

parts without danger of overflowing or leaking, and which will be easily vadjustable to different sizes as required. v

Still another object of the invention'is a syringe of this character in which the shield, through which the return iiow passes, will eifectually close the mouth of the vagina and prevent leaking, while at the same time will be comfortable when in position and not cause any inconvenience. And the invention also aims to generally im "rove devices of this class and to render ein more useful and commercially desirable.

With these and other objects in View as will more fully appear as the description proceeds, the -invention consists in theconstructions, arrangements, and combinations of the parts that I shall hereinafter more fully describe and claim.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawing, in which z v Figure 1 is a sectional view of my improved expanding vaginal syringe, parts being shown in elevation and other parts broken away. Fig. 2 is a detail plan view of one of the parts of the shield. for holding the dilater lingers at one end in an adjustable manner; Fig. 3 is a fragn'ientary view illustrating one end of the device; Fig. 4

is Aa cross-sectional view through the eX- panding element of the syringe; Fig. is a detail sectional -view of a modified forni ot the shield, hereinafter specifically described;

nated in the accompanying,drawing by like reference characters.

Referring to the drawing, the numeral 1 syringe, on one end of which is detachably mounted the expander' head 2, secured on the tube in any desired way so that one head may be removed and replaced by another of larger or smaller size, as required. The head2 is formed with any desired number of jet orifices 3 which are preferably obliquely disposed', as best seen in Fig. l, whereby the healing and cleansing Huid, as it passes out through said orifices, will be in the form of a whirling spray. Preferably the body of the tube itself is also formed with jet orifices, designated 4;, designed to enlarge the flushing area of the device.

The 'spray tube 1 is provided near one end with laterally projecting handle arms 5 lby which it may be manipulated, and at suclr end with a nipple 6 designedfor the attachment thereto of a supply tube 7 leading from a compression bulb 8.

Mounted upon the spray tube l is a capplate 9, the saine being formed with a nipple 10 to which isjgattached a suction tube 11 leading to a suctionbulb 1Q. -The cap-plate 9 is formed with a marginal flange 13 by which it is designed for detachable connection to the grooved riin 14 of the body pordesignates the spray tube`of my improved'- tion 15 of the shield. This body portion,

in the present embodiment of the invention. may be formed of either solid or hollow` (pneumatic) or soft or hard rubber, and it is to be particularly noted that the rim 14- of the body portion -is formed with an open groove 16, whereby when the rim is pressed against the mouth of the vagina. a. suction effect will be produced and all leakage prevented. '.lhe inner end of the body portion of the shield formed. preferably, with an outwardly projectii'ig flange 17, designed under ordinaryY .'onditions to engage, yieldingly, the mills of the vagina, without 1inconifortable plwsure, and yet4 with suffivagina suitably pressed apart.

cient pressure to assist in preventing the medicament from passing, in its outward- 1 flowgaround the outside of the shield.

The uter ends vof the dilating fingers 18 are turned somewhat outward and then in' ward as indicated at 21, the inwardly turned extremities fitting within radial grooves 22 .that are formed in a retaining disk 23 -apertured to fit upon the spray tube 1, said extremities being clamped between said disk and the cap-plate 9 by means," of screws 24,

whereby the outer end of the dilator may be laterally venlarged or contract d, as required. From the foregoing description, together with the accompanying drawing, the operation of my improved expanding vaginal syringe will be apparent. In the practical use of the device, a head of suitable size is slipped upon the end of the spray tube 1 and the outer ends'of` the dilating fingers 18 are adjusted as required, and the device inserted, in contracted condition, into the vagina. The spray tube l is then pushed relatively inward, vwhereupon the inner ends of the fingers 18 will ride upon the head2 and be expanded so as to hold the walls of the One of the bulbs is then compressed and the other perj mitted to expand, whereby the healing and cleansing fiuid will be forced into the or' gan and thoroughly Hush the same, returning through the shield and out through the suction tube 11. The shield will edectually prevent any leakage, and consequently the device can be used without fear of soiling bed or garments.

While the accompanying drawing illustrates the preferred embodiment of my 1nvention, it is to be understood that the invention is not limited thereto, butthat various changes may be made in the construction, arrangements,l and proportions of the proved vaginal syringe possessing,' a1nong other advantages, thefollowing: The inner ends of the dilater: fingers are so formed that theywill not be liable to catch in the folds of the vagina when withdrawing the:

device, the flushing device is so formed and arranged that its area and whirling spray will force everything out of the vagina instead of in it, the shield is so formed that it will effectually seal the mouth of the vagina, when the device is properly applied, and thus prevent any leakage, and the dilating lingers and the interchangeable head will enable the device to be easily adjusted to different sizes as required. i

The dilater fingers may bemade either, as illustrated in- Figs. 1, 3 and 7, or, asl illustrated in Fig. 8. It is to be understood that the fingers/in Figs. 1, 3 and S'are thesame, y Y

A854 ouble linesin Figs. f' v1 and 3. It will, therefore, be understood the scale being so small however, that it is impossible to show the that in each form or embodiment of the dilater-fingers, they are formed of wire which is doubled upon itself at a middle point and which is squared at'one extremity, as indicated at 19, l'or is round, as indicated at 19 and filled inv square, as indicated at 19b in Fig. 8. In each embodiment of the dilating fingers, they are equally spaced apart throughout their length and where they are f connected together at the relatively free extremities, they are square anddo not 'approach each other, the inner edges of the two v lengths of the doubled wire being equally spaced apart throughout the length of the fingers, whereby no wedge-shaped space will be provided, which would be liable to catch the tissue and tear or otherwise injure it when the device is withdrawn. If desired, the shield may have its outery flange provided with arbead, as indicated at 14h, as clearly illustrated inFig. 6. j f

Vhat I claim is 1. A device of the character described, em-Y bodying a spray tube having a discharging head, dilating fingers and supports therefor at one end of the fingers, each of said fingers being formed of round wire doubled upon itself at a middle point to form spaced portions connected together at their free inner extremities, straight andparallel for the major portion of'their length and thence curved inwardly .toward the head, the transverse portions of the wire which connect saidl members together at their free inner extremities presenting on their inner edgesA right angles said members being withthe adjoining edges of the said spaced members, whereby all tapering or wedgef shaped spacesat the free inner extremities of the nger's will be avoided and` all liability of injuring the tissue upon the withdrawal .of the device precluded.
